Letters Patent No. 114,117, dated April 25, 1871.

IMPROVEMENT. lN SPARK-ARRESTERS.

The Schedule referred to in these Letters Patent and making part: of the same.

being bad to the accompanying drawing making part of this specification, in which the figure is a sectional elevation.

This invention has for its object to arrest the sparks, oinders, 850., that come from the tire-fines of a steam-boiler, and hold them in a chamber provided for their reception until they become dead and harmless.

The invention particularly consists in a.hinged box provided with a perforated flange applied to the end of a steam-boiler in such connection with the tube or funnel. through which the exhaust-steam enters the smoke-stack. that the momentum acquired by the cinders and sparks will cause them to enter said box, where they will be retained and thus rendered harm less.

Referring to the drawinga is a boiler.

b, the furnace for the same.

- c, fire-fines traversing-the boiler from the furnace to the rear end.

d, a space in the boiler beyond the fines c and waterspace, and directly beneath the smoke-stack e.

f, a pipe projecting into the space 01 and extending nearly to the bottom of the Smokestack, thefunction of said pipe being to discharge into the smoke-stack waste steam from the boiler, with which the pipe is connected in any suitable manner, for the purpose of increasing the draught.

A is a cylindrical box, hinged at its upper side to the end of theboiler, and communicating with the space (i, from which it is separated only by the flange h. The momentum acquired by sparks, coals, &c., during their passage through the fire-fines carries them into the box A, which retains them until they are burned out.

Whenever a quantity of refuse matter of this description accumulates in the box, the latter maybe raised on its hinges so as to discharge its contents.

' If the box were not employed the sparks wouldfly upward through the chimney, as they do in the case of boi lers not provided with an arrester.

Hailing thus described my invention,

\Vhat I claim as new, and desire to secure by Letters Patent, is-

The improved spark--arrester, consisting of the hinged box A and apertured flange 11,, arranged with the tube], flues c c, and smoke-stack e, as herein shown and described, to operate as set forth,

To the above specification of my invention I have signed my hand this 28th day of September, A.". D. 1870.
